@zongyi-li Thank you very much for your response. Still not clear about point 2, but let me think about it. Perhaps it will be useful for me to take a...

About the errors reported in the edit above: The position and velocity errors are reported at the final time. Perhaps the errors at the final time are not a monotonic...

Thank you, that's interesting.

But still, a velocity error of 12.33 (1233% !!!) seems too high.

Thanks. I was under the impression that ```-rvdim 40 ``` introduces a reduced basis for the velocity field as well.

Hi, @axla-io I've used the example non-linear elasticity code without modifications. https://github.com/LLNL/libROM/blob/master/examples/prom/nonlinear_elasticity_global_rom.cpp I've used the instructions for the "Nonlinear elasticity, PROM" without modification https://www.librom.net/examples.html Except that I've replaced XXX with...

Hi @axla-io Sorry for the late reply. Here is what seems to happen. With -rvdim 40 Elapsed time for time integration loop 350.778 Relative error of ROM position (x) at...

> Also if you have time, try to see if you get the same behavior for -sc smaller than 1, like -sc = 0.15 and 0.25 for the offline phase...

@chldkdtn I've been going through the nonlinear elasticity example line by line https://github.com/LLNL/libROM/blob/master/examples/prom/nonlinear_elasticity_global_rom.cpp What I'd like to know is what `*Hsinv` which is computed by the sampling routines `S_OPT`, `GNAT`...
